d2 5u tracks

How many hours are you going to put on it? The cheapest option would be to find a parts machine with better tracks. Use the track and part the rest.

My understanding is that usually a track shop (if there is one in your area still) would not attempt to replace the pins and bushings once the bushings are worn too thin or cracking up. There are tremendous forces involved in disassembling the track components and sudden failure of the worn bushings under pressure is dangerous. Someone may know more about it than me and I would appreciate being corrected if I am wrong.

On the other hand, I could see how someone who had more time than money and had the right shop equipment could disassemble the tracks in a more time consuming but safer way. Then the links could be delivered to a shop where they could be reassembled using new bushings and pins.

The big question is how much meat is left on the rails and how much time and money do you want to spend on it. For that matter the rails can even be built up with weld. I am not sure you could value your time at anything much more than zero and buy the welding rods/wire etc and still come out ahead on rebuilding a set of rails.

Thread discussing NEW tracks
http://www.acmoc.org/bb/showthread.php?25339-New-D2-track-chains

I don't own a D2 and know little about them, BUT, I did have a discussion with a knowledgeable gentleman (who is restoring the first D2 ever built) who went into a lot of detail on how to use chains off of a D3. I can't remember his "handle" when he posts here so I can't give it. Lots of folks here will know of whom I speak. I will be contacting his again for a friend who also needs tracks for his 3j so will get the details pinned down better at that time.

I was also told by a track shop that they won't touch tracks with bushings broken or wore through.
